People magazine broke the news of a rift between the brothers -- Nick, 21, Joe, 24, and Kevin, 25 -- on Wednesday and reported a blow-up over the weekend as the catalyst for the cancellation. The 19-date trek was to have begun Friday in Upper Darby, PA.

The trio had been working on their fifth album, “V,” and the tour was to have previewed tracks from the forthcoming record.

Since their last album, 2009’s “Lines, Vines and Trying Times” -- their last under Hollywood Records, the label that sent them into teen pop superstardom -- they have gone down different paths. Kevin got married and launched a reality show with his wife (they are expecting their first child), Joe and Nick went solo to drastically different results, and they’ve racked up their fair share of more adult-friendly headlines as they've transitioned into adulthood (shirtless selfies, bombshell girlfriends, etc.)

Earlier this year, they launched the first legs of the tour, which wrapped with a sold-out show at Gibson Amphitheatre in August.

Although thousands of screaming teenagers packed Gibson armed with signs, JoBros merchandise and the inability to curb their shrieks, it was clear that the trio were long removed from their days of guitar-driven innocuous pop. The set showcased them as a more sleek, pop-oriented garage band focused on building sturdy rock-pop grooves without overwrought arena frills.

The new music they previewed packed a harder punch than some of their earlier, sweeter pop melodies -- but there was an array of tastes present. Their driving, drumline-soaked single “Pom Poms” was steeped in the pure pop sexiness Joe flirted with on his solo debut, while “The World” showed Nick’s knack for bluesy, John Mayer-inspired pep, and crowd standout “What Do I Mean to You” was a moody rock-electro mid-tempo that could have easily been crafted by the Weeknd.

“All three have different views on the music,” the rep added.

“V” was to be rolled out in suites of songs, but the future of the album -- and the band -- “remains to be seen.”
